To all 'whom it may concern.'

Be it known thatl, MiLFon'D SHIN'GLER, a `citizen of the United States, residing at Ashville, in the county of Cambria and State of Pennsylvania, have invented new and useful Improvements in Rock and Coal Drills, of which the following is a specification.

This invention is an improved hand drill for use in drilling rock,coal and the like and in mining operations, the object of the invention beingto provide an improved machine of -this kind 4which may be readily operated byone man, which is simple in construction, is strong and durable, and is not likely to get out otorder.

Another object of the invention is to effect improvements` .in the construction of the main .frame to enable the main frame to be vertically adjusted as may be required by the distance between the ii'oor and the roof of the mine in which the drill is used.

Another object `is to provide a carriage which is vertically movable on the mam frame and which carries the drill frame and enables the drill to be operated at any desired elevation.

With the.above and other objects in view the invention consists inthe construction,

combination and arrangement of devices hereinafter described an claimed.

In the accompanying drawings Figure 1 is a side elevation of a rock and coal drill constructed and arran ed in accordance 'with ymy invention an .showing the same set up ready for operation.

Fig. 2 is a vertical sectional lview of a portion of the same on a larger scale. i'

Fig. 3 is an elevation of the same, partly in section on a plane at right-angles to that of Fig..2.

Fig. 4 is a horizontal sectional view on v the plane indicated by the4 line 1 -4 of Fi 5 is a similar view on the plane indicate by the line 5-.-5 of Fig. 1.`

Fig;Y 6 is a ldetailed sectional'view of the base and ,thelower portion of the mainV frame. .j

Fig. 7 is asimilar view of the head and the upper orti'on of the upper member lof the main rame. v,

Figs..8 to 14, inclusive are detailed views. The main frame A1j .which serves as a stanchion to support the drilling machine 4tacha and which is adapted to be arranged vertically in a mine and between the oor and roof of the mi.ne,comprises a lower member 2 and an upper member 3. The lower member is provided at its lower end with vertical openings 4 which receive tenons or studs 5 which project upwardly from the base 6. A bolt 7 passes transversely through an opening near the lower end of the frame member 2 and through openings in the tenons and studs and coacts with the tenons or studs to securely detachably fasten the lower end of the main frame member 2 to the base. The base is provided `at the corners with downwardly extending legs 7', which have pointed lower ends to engage the floor of the mine.

The upper member 3 is provided at` the lower end with downwardly extending guide bars 8 whichoperate in vertical openings in the upper end of the frame member 2. I he upper ends of said guide bars are detachably fitted in openings in the lower end of the member 3 and are secured to said member by bolts 9. Hence the member 3 is connected t0 the member 2 for vertical of the member 3 and also in a bearing 13 which is detachably secured in said member `3 by bolts 14;. A beveled gear 15 is se` cured near the upper end of the screw 'shaft 11 and is engaged by a similar gear`16 on a shaft 17, which shaft is mounted in bearings ina pair of plates or bars 18 which are secured to and extend transversely across the frame member 3 at op osite sides'of the latter. A hand cra-nk 19 is providedwhich' may be attached to the shaftV 17 and turned to cause the gears to rotate the screw 10 and hence cause said screw to ad'ust the frame member 3 vertically as may e required b the height o f the mine. head 20 whic is identical in construction with the base 5 and which has upwardly extendin pointed le s 21to engage the mine roo is debly secured Vto the upper end of the frame member 3 by tenons" or studs 22 which between the sidesofthe lower framed-,nember 2 and ijs-provided von its front side near engage in openings in the upper end of the member 3 and are secured to said member by a bolt 23.

When it is necessary to still :further increase the length or height of the main frame a sectional frame member 24 employed which is secured on the upper cud of the member 3 by vstuds .or tenons 25', the head having been removed from the upper end of the member 3 and secured by its studs ortenons on the upper end of tho member 24.

.The vlower frame member 2 is. provided with a-vertical slot 25 in each `side and is also provided on each side with a rack 26. The racks are detaohably scoured in place by bolts 27. A. carriage 28 has its vertical sides '29 slidably arranged on the outer surfaces of thcsides oif the member 2 and is provided at itsupper end with horizontally arranged arms 30 each of `which has a vertical slot 3l to clear and receive one side of the frame member 2 and open at the 'front end. A cross lyoke or bar 32 ,connects the arms 30 together, bears against the front side of the frame .member 2 and is detachabl'v secured to the arms 30' of the Carriage bya bolt 33. A bolt 34 connects the sides of the carriage, passes through openings therein and also passes through the slots 25 so thatthc carriage is mounted on the lower member of themain `frame. for vertical adjustment. A vertical. series of openings are provided in the sides of the carriage for the bolt 34 to permit vertical adjustment of said bolt with respect to the carriage. The lower ends ofthe sides of. the carriage are provided with openings for the reception of the reduced ends of a cross bar 3G` 4Said cross bar passes through and is slidably movable in the slots 25 and carries a screw 37 which, is employed to adjust the drill frame 4angul arly inv a verticalplane and to hold the drill frame atany required adjustment.

,The drill frame 38 is slidably arranged its. upper. .end with bearings 39 `through which .the bolt 34;- extends .said bolt1 serving Aas.the supportirmr pivot for the. drill frame.

The rear endoflthe adjusting .screw 3.7 hears againstthe front' side of the drill fra-me. The front. and rearsides of the dri-ll -frame are-,spaced apart andare connccteditogether attheir upper and lower ends by hl'ocksr39 `xtrlricli are secured by bolts 40., A screw shaft 4:1. for. .o.perating the drill or auger 42 passes through and: is longitudinally and revoluhly.1n'o.unte d in Unthreaded openings in. the

front and rear sides of. the drill framea-nd .also passes. through. and engages. threaded openings in.,members 4,-3. wlii`ch, are secured by bolts.. 44 to; the .liront and rear sides of the drillluframe.. A spur gear ll5 is spl-ined on tl1e.. screiv s haft 41 asiat 46 for rotation with the screw shaft and to permit the screw shaft to move longitudinally through said gears.V The gear has a hub which is mounted m a bearingI ll? with which the rear side of the drill -frame is provided. A shaft -lS is arranged-below and parallel with the drill shaft and is mounted in bearings 49 which arc-bolted to the front and rear sides olf the drill frame.' A gear 50 which engages the gear 45, is fast on the shaft 49, a Worm gear 51 also fast on saidshaft Said worm gear is engaged lby a-Worm 52 ona shaft 53, which shaft is mountedirr bearings 541 which are bolted Ato theinnerside ofthe rear side of the drill frame. A suitable hand crank l 55 may be attached to said shaft-and used to :manually turn the latter and hence cause the Worm7 Worm gear and the gears 50, Ll5 to rotate the drill .screw shaft. Hence the drill or auger may be turned as required to drill or bore in. the rook. or coal and owing to the provision of the threaded .members 4P) with which said shaft l.Ilis threa'dedly cngaged .and the provision of the .splined n .iountineT of the gear 45 on said shaft, said shaft Will also be movable longitudinally as required to :feed thedrill or auger to the work. Thedrill .or auger. may be arranged to .Work at any4 desired-.inclination or horizontally .by appropriately adjustingthe drill frame by ,means of .the hand .screwv 37 lomove the carriage andhence also the .drlll frame andthe drilloperating mecha- .nism up or down on the. malin frame .mem-

ber 2 as. may .be required I provide a shaft .57 which. is. .mounted` in bearings in thearms 30 of the carriage and is .provided with pinions 5,8 which engage the racks. Asuitable hand crank 59 is provi-ded. for this shaft to enable it to be manually turned. To secure thecarriage at-any. desired elevation I provide avertically arranged -serewv 60 whichuengages a threadedfopeningina bearing. .61 on one sideof theltopof,the-carriage.

Said .screw may be engaged with o r-l-,disen gaged fromA astopfgear 62 wthwhich the shaft 57 is. rovid-ed.
